STOPPER Chicago, Ill., assignor of 2 Claims.

The present invention relates to new and useful improvements in stoppers particularly for bottles of catsup, sauce, etc., and has for its primary object to provide, in a manner as hereinafter set forth, a stopper embodying novel means whereby the content of a bottle may be conveniently dispensed under pressure.

Another very important object of the invention is to provide in a bottle stopper of the type including a dispensing tube, a control valve therefor and a pressure pump, novel means for connecting the valve to the pump for actuation to open position thereby.

Other objects of the invention are to provide a bottle stopper of the character described which will be comparatively simple in construction, strong, durable, highly efi'icient and reliable in use, compact, sanitary and which may be manufactured at low cost.

All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specification, taken in connection with the accompanying drawings wherein like characters of reference 25 designate corresponding parts throughout the several views, and wherein:

Figure 1 is a view in side elevation, showing an embodiment of the invention mounted in a bottle.

Figure 2 is a view in vertical section through the invention.

Figure 3 is a detail view in elevation of the valve disc.

Figure 4 is a detail View in elevation of the pump plunger.

Figure 5 is a detail view in side elevation of the rod which connects the valve disc to the pump plunger.

Figure 6 is a top plan view with the plunger, discharge spout, etc., omitted.

Referring now to the drawings in detail, it will be seen that the embodiment of the invention which has been illustrated comprises a plug of suitable material which is designated generally by the reference numeral I. As illustrated to advantage in Fig. l of the drawings, the plug l is adapted to be inserted in the neck 2 of a catsup, sauce or other bottle 3.

Referring now to Fig. 2 of the drawings, it will be seen that the plug I is formed to provide a dispensing tube 4 extending above and below said plug, said tube terminating, at its upper end, in a curved discharge spout 5. Hingedly mounted in the upper portion of the dispensing tube 4 is a control valve 6 in the form of a disc which is swung upwardly to closed position by a spring 1. A hook 8 is provided on the lower side of the valve disc 6, the purpose of which will be presently set forth.

On one side of the dispensing tube 4 is a pump which is designated generally by the reference numeral 9. The pump 9 includes a barrel I0 in the vertical bore II of which a manually operable plunger or piston I2 is mounted for reciprocation. A finger or thumb receiving head I3 in the form of a disc is provided on the upper end of the plunger I2.

The barrel II] of the pump 9 has formed therein, at an intermediate point, a vertical groove or channel I4 which communicates throughout its length with the bore II. Operable in the groove or channel I4 is a hook I5 which is mounted on the plunger I2 at an intermediate point. Extending slidably through the barrel I0 from the dispensing tube 4. into the groove or channel I4 is a rod I6 of suitable resilient material which terminates in angularly projecting end portions I1 and I8. The end portion ll of the rod I6 is operatively engaged with the hook 8 of the valve disc 6. The end portion I8 of the rod I6 is located in the path of the hook I5 for engagement thereby for opening the valve 6 when the plunger I2 is moved downwardly.

It is thought that the operation of the invention will be readily apparent from a consideration of the foregoing. The valve 6 in the dispensing tube 4 is normally maintained in closed position by the spring I. The device is mounted firmly but removably in the neck of the bottle. Then, when the plunger I2 is forced downwardly air from the bore I I of the pump 9 is compressed in the bottle. It will be observed that the dispensing tube 4 extends to a point adjacent the bottom of the bottle. As the plunger I2 moves downwardly the hook I5 thereon engages the end portion I8 of the rod I6 and the valve 6 is swung downwardly to open position thereby permitting the discharge of the content of the bottle under pressure. When the plunger I2 is released the spring 1 re- 45 turns the valve 6 to closed position. If desired, a spring may also be provided for returning the plunger I2 to raised position.

It is believed that the many advantages of a bottle stopper constructed in accordance with the present invention will be readily understood and although a preferred embodiment of the device is as illustrated and described, it is to be understood that changes in the details of construction and in the combination and arrangement of parts may be resorted to which will fall within the scope of the invention as claimed.

What is claimed is:

l. A bottle stopper of the class described comprising a dispensing tube, a valve in said dispensing tube, a pump including a barrel paralleling the dispensing tube, a plunger slidably mounted in the barrel, a rod extending from the dispensing tube into the barrel, said rod having one end connected to the valve, and coacting means on the rod and plunger for connecting said rod to said plunger for opening the valve when the plunger is moved in one direction, said means including angularly projecting end portion on therod, and a hook member on the plunger engageable with said end portion. a

2. A bottle stopper of the class described comprising a plug adapted to be mounted in the neck of a bottle, a dispensing tube extending through said plug and terminating, at one end, in a curved discharge spout, a control valve hingedly mounted in the dispensing tube, a spring operatively connected to the valve for closing same, a pump including a barrel having a bore paralleling the dispensing tube, said barrel further having a channel therein communicating throughout its length with the bore, a manually operable plunger slidably mounted in the bore, a rod extending from the dispensing tube into the channel and having one end operatively connected to the valve, an angularly projecting portion on the other end of the rod in the channel, and a hook member on the plunger operable in the.channel and engageable with said angular portion of the rod for opening the valve when the plunger is moved in one direction.
